# ContactsContract.DataUsageFeedback

`public static final class ContactsContract.DataUsageFeedback`
`extends Object` ``

java.lang.Object
↳ | android.provider.ContactsContract.DataUsageFeedback

This class is deprecated.
Contacts affinity information is no longer supported as of Android version `Build.VERSION_CODES.Q`. Both update and delete calls are always ignored.

API allowing applications to send usage information for each `Data` row to the Contacts Provider. Applications can also clear all usage information.

Caution: If you publish your app to the Google Play Store, this field is obsolete, regardless of Android version. For more information, see the Contacts Provider page.

With the feedback, Contacts Provider may return more contextually appropriate results for Data listing, typically supplied with `ContactsContract.Contacts#CONTENT_FILTER_URI`, `ContactsContract.CommonDataKinds.Email#CONTENT_FILTER_URI`, `ContactsContract.CommonDataKinds.Phone#CONTENT_FILTER_URI`, and users can benefit from better ranked (sorted) lists in applications that show auto-complete list.

There is no guarantee for how this feedback is used, or even whether it is used at all. The ranking algorithm will make best efforts to use the feedback data, but the exact implementation, the storage data structures as well as the resulting sort order is device and version specific and can change over time.

When updating usage information, users of this API need to use `ContentResolver#update(Uri, ContentValues, String, String[])` with a Uri constructed from `DataUsageFeedback#FEEDBACK_URI`. The Uri must contain one or more data id(s) as its last path. They also need to append a query parameter to the Uri, to specify the type of the communication, which enables the Contacts Provider to differentiate between kinds of interactions using the same contact data field (for example a phone number can be used to make phone calls or send SMS).

Selection and selectionArgs are ignored and must be set to null. To get data ids, you may need to call `ContentResolver#query(Uri, String[], String, String[], String)` toward `Data#CONTENT_URI`.

`ContentResolver#update(Uri, ContentValues, String, String[])` returns a positive integer when successful, and returns 0 if no contact with that id was found.

Example:

     Uri uri = DataUsageFeedback.FEEDBACK_URI.buildUpon()
             .appendPath(TextUtils.join(",", dataIds))
             .appendQueryParameter(DataUsageFeedback.USAGE_TYPE,
                     DataUsageFeedback.USAGE_TYPE_CALL)
             .build();
     boolean successful = resolver.update(uri, new ContentValues(), null, null) > 0;

Applications can also clear all usage information with:

     boolean successful = resolver.delete(DataUsageFeedback.DELETE_USAGE_URI, null, null) > 0;

## Summary

### Constants
`String` | `USAGE_TYPE` Name for query parameter specifying the type of data usage.
`String` | `USAGE_TYPE_CALL` Type of usage for voice interaction, which includes phone call, voice chat, and video chat.
`String` | `USAGE_TYPE_LONG_TEXT` Type of usage for text interaction involving longer messages, which includes email.
`String` | `USAGE_TYPE_SHORT_TEXT` Type of usage for text interaction involving shorter messages, which includes SMS, text chat with email addresses.

### Fields
`public static final Uri` | `DELETE_USAGE_URI` The content:// style URI for deleting all usage information.
`public static final Uri` | `FEEDBACK_URI` The content:// style URI for sending usage feedback.

### Public constructors
`DataUsageFeedback()`

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
